METHOD OF WEAVING WIRE.

SPECIFICATION forming part of Letters Patent No. 704, dated y 1902-Application filed March 28, 1901. Serial No. 52,907. (No specimens-l Toall whom it may concern:

Be it known that I, CHARLES WV. JAMES, a citizen of the United States,and a resident of the city and county of Philadelphia, State ofPennsylvania, have invented certain new and useful Improvements inMethods of Weaving Wire, of which the following is a specification.

My invention relates to improvements in processes for weavingwire-cloth, and more particularly to improvements in processes forweaving wires of sectional area and stiffness too great to be woven inthe ordinary loom and heretofore woven by hand.

The accompanying drawings, forming part of this specification, and inwhich similar letters of reference indicate similar parts throughout theseveral views, show a means for weaving wire according to my process.

In the drawings, Figure 1 is a side elevation of the bending-dies open;Fig. 2, a similar view, the dies being closed; and Fig. 3, a frontelevation of the parts shown in Fig. 2 with the guide-block removed.

In. carrying out myinvention straight warpwires are arranged parallelwith one another and fed in the direction of their length with astep-by-step movement to the dies. After each forward movement of thewarp-wires the adjacent portions of the consecutive wires arepermanently bent in alternately opposite directions, thereby forming ashed consisting of a series of loops extending transversely of thefabric, and a weft-wire is placed in each shed or series of loops whenformed.

Referring to the drawings, which show a pair of dies suitable for makinga reverse bend in each warp-Wire at each operation of the dies, therebyforming simultaneously two sheds or series of loops, it indicates theupper dies and b the lower dies, carried in suitable holders 0 and d,one or both of said dies being movable toward and from the opposite die.

6 indicates the warp-wires; f, the cross or weft wires. Before passingto the dies at b and preparatory to being bent or crimped the warp-wirespass, preferably, through a perforated guiding-block g, which holdstheir unbent portions firmly during the action of the dies. The dies areso formed and placed that every other strand of the warp-wires will bebent or crimped exactly alike-forinstance, first upward and thendownward-while the intermediate strands will be each bent exaotly alike,but in opposite directions from the first strands-that is, firstdownward and then upward-the bends being arranged so that the upward oneon one wire will be directly opposite the downward one on the next wire,and so on. In each die ah is formed a recess 0, through which when thedies are closed may be passed the weft or cross wires f, these openingsbeing formed in the outermost parts of thedies. The cross-wires whenpassed in through the openings also pass in between the loops formed bythe dies in the wires. When the dies are separated, the cross-wires areleft in between the warp-wires, which are afterward flattened down, soas to bind tightly against the cross-wires, by blocks h and h, which aresecured to the holders 0 and d, respectively, immediately in the rear ofthe dies, and, if desired, the cross-wires themselves maybe bent so asto lock against the warp-wires; but in the process of flattening downthe cross-wires are bent, forming a lock sufficient for all ordinarypurposes. My process consists, therefore, in bending the warp-wires indies, one up and the next adjacent one down, to form loops and whilestill held by the dies in passing in between-said loops the cross-wires,and finally, if necessary, in flattening down said warp-wires upon saidcross-wires and in bending said cross-wires so as to lock against saidwarp-wires.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The herein-described process of weaving heavy wire, which consists inarranging straight Warp-wires parallel with one another, moving saidwarp-wires forward step by step in the direction of theirlength,permanently crimping the consecutive wires in suitable dies inalternately opposite directions after each movement, thereby forming aseries of loops extending transversely of the fabric and insertingaweft-wire into each shed or series of loops thus formed.

2. The herein-described process of weaving heavy wire, which consists inarranging straight warp-wires parallel with one another,

moving said Wires step by step in the direction of their length, formingsimultaneously two series of loops extending transversely of the fabricafter each movement by making a permanent reverse bend in each Wire, theadjacent bends in consecutive wires extending in alternately oppositedirections, and insert ing a Weft-wire into each shed or series of loopsthus formed.

3. The herein-described process of weaving heavy Wire which consists inarranging straight warp-wires parallel with one another, moving saidwarp-wires forward step by step in the direction of their length,permanently crimping the consecutive Wires in suitable dies inalternately opposite directions after each movement, thereby forming aseries of loops extending transversely of the fabric and inserting aweft-Wire into each shed or series of loops thus formed, and thencompressing 20 the Warp-wires upon the weft-wires.

4. The herein-described process of weaving heavy Wire, which consists inarranging straight warp-wires parallel with one another, moving saidWires step by step in the direction of their length, formingsimultaneously two series of loops extending transversely of the fabricafter each movement by making a permanent reverse bend in each Wire, theadjacent bends in consecutive wires extending in alternately oppositedirections, and inserting a weft-Wire into each shed or series of loopsthus formed, and then compressing the warp-Wires upon the weft-wires.
